Radon in the basement

I have a small radon problem too.

Tests past 2 years
2008: 3.5
2009: 4.6 1st floor 6.0 Basement

Going to do it just in case...piece of mind. If I have to sell, I will HAVE to do it so....

Both neighbors on the side of my house have them. Spoke to CEO of the company that did it, he came out to my house. Great guy, he even told me that my levels are very low and basically said "if you 10 people lived in your basement for 70 years there is a 70% chance that 1 person MIGHT get lung cancer.

He said if it was few hundred like he sees all the time, he would strongly recommend. Quoted me $1100.

I'm going to do it for piece of mind. I will not pay $1100 for that piece of mind though. It's about $200-400 to do it yourself (for a basic set up). If you have a big problem you might need a better fan.

I've been researching Radon Mitigation systems and it's a pretty straight forward procedure. First you have to make sure you can even DIY, some states HAVE to have a certified tech install it.

In CT I'm clear.

Biggest part of the job is really just drilling through the slab + House. Rest is piece of cake.

I'm about to do this job in few weeks so I can do a little write up.

Here is what I gathered so far.For those that have experience please confirm below.

PS Found a lot of videos on you tube....

- Check if you need Cert Tech to do the job in your state!

- Get a quote/plan lay out when you call your local radon specialist.

- Drill 3" or 4" diameter hole in your slab about a 12" away from foundation wall. Need Hammer Drill with Diamond Drill bit. Home depot rents both if you don't have connects. Might also need jack hammer.
NOTE: If you get a nice even hole (preferable) you will only need some polyurethane caulk. If it's not even you will need to seal it and hydraulic cement. Point is, get it as close to size you are going to use.

- After you drill a hole, check what you have under, gravel/sand/mud etc it ALL makes a difference on the Fan you will need to buy.

Recommended by the company CEO. They gave me a number to their retailer that told me to call back once I know what's under my house.

You also have other choices Fantech makes these...do your research.

- Mount Fan run PVC piping up above your roofline using mounts (outside/inside). Will need external electrical outlet!
- Drill 3" or 4" hole on side of house
- Dig a 20" diameter pit after drilling hole in your foundation
- Mount PVC pipe on the bottom line of the foundation
- Caulk the pipe with foundation (use polyurethane)
- Install a pressure meter
- Drill 1-2 holes in other places around your basement and test with smoke pen when the fan is on. Seal with caulk.
